  1. Web Development & Design Foundations with XHTML Chapter 8Key Concepts

  2. Learning Outcomes • In this chapter, you will learn how to: • Create a table on a web page • Apply attributes to format tables, table rows, and table cells • Format the layout of a Web page with a table • Use nested tables • Use CSS to configure an XHTML table

  3. Table • Tables are commonly used on Web pages in two ways: • To organize information • To format the layout of an entire Web page

  4. XHTMLUsing Tables • Composed of rows and columns – similar to a spreadsheet. • Each individual table cell is at the intersection of a specific row and column. • Configured with <table>, <tr>, and <td> elements

  5. XHTMLTable Elements • <table> Element Contains the tableCommon attributes: border, width, align • <tr> ElementContains a table row • <td> ElementContains a table cell • <caption> Element • Configures a description of the table

  6. XHTMLTable Example <table border="1"><caption>Birthday List</caption> <tr> <td>Name</td> <td>Birthday</td> </tr> <tr> <td>James</td> <td>11/08</td> </tr> <tr> <td>Karen</td> <td>4/17</td> </tr> <tr> <td>Sparky</td> <td>11/28</td> </tr> </table> Birthday List

  7. XHTMLTable Example 2 <table border="1"> <tr> <th>Name</th> <th>Birthday</th> </tr> <tr> <td>James</td> <td>11/08</td> </tr> <tr> <td>Karen</td> <td>4/17</td> </tr> <tr> <td>Sparky</td> <td>11/28</td> </tr> </table> Using the <th> Element

  8. XHTMLCommon Table Attributes • align (deprecated) • bgcolor (deprecated) • border • cellpadding • cellspacing • summary • width • Percentage or pixels?

  9. XHTMLCommon Table Cell Attributes • align • bgcolor (deprecated) • colspan • rowspan • valign • height (deprecated) • width (deprecated)

  10. XHTMLcolspan Attribute <table border="1"> <tr> <td colspan=“2”>Birthday List</td> </tr> <tr> <td>James</td> <td>11/08</td> </tr> <tr> <td>Karen</td> <td>4/17</td> </tr> </table>

  11. XHTMLrowspan Attribute <table border="1"> <tr> <td rowspan=“2> <img src=“cake.gif” alt=“cake” height=“100” width=“100” /></td> <td>James</td> </tr> <tr> <td>11/08</td> </tr> </table>

  12. Accessibility and Tables • Use <th> elements to indicate column or row headings. • Table element summary attribute • provide an overview of the table contents • Complex tables:Associate table cell values with their corresponding headers • <th> tag id attribute • <td> tag headers attribute

  13. <table border="1" width="75%" summary="This table lists my educational background. Each row describes educational experience at a specific school."> <tr> <th id="school">School Attended</th> <th id="years">Years</th> <th id="subject">Subject</th> <th id="degree" >Degree Awarded</th> </tr> <tr> <td headers="school">Schaumburg High School</td> <td headers="years">2000 - 2005</td> <td headers="subject">College Prep</td> <td headers="degree">H.S. Diploma</td> </tr> </table>

  14. <table border="1" width="75%" summary="This table lists my educational background."> <thead> <tr> <th>School Attended</th> <th>Years</th> </tr> </thead> <tbody> <tr> <td>Schaumburg High School</td> <td>2005 - 2009</td> </tr> <tr> <td>Harper College</td> <td>2009 - 2010</td> </tr> </tbody> </table> Table Row Groups • <thead>table head rows • <tbody >table body rows • <tfoot> table footer rows

  15. Checkpoint 8.1 1. Describe two reasons to use tables on a web page. 2. Describe the difference between the cellpadding and cellspacing table attributes. 3. Describe one coding technique that increases the accessibility of an XHTML table.

  16. XHTML– Using a Table toFormat a Web Page <table border="0" width="80%"> <tr> <td colspan="3"> <h1>This is the banner area</h1></td> </tr> <tr> <td width="20%" valign="top"> Place Navigation here</td> <td width="10">&nbsp;</td> <td>Page content goes here</td> </tr> </table>

  17. Additional Table Layouts

  18. Flexible & Fixed Table Widths • Fixed Table: • Table width attribute in pixels • http://www.redbox.com • http://www.yankeecandle.com • http://www.league.org • Flexible Table: • Table width attribute in percenthttp://www.co.door.wi.gov

  19. Nested Tables • Outer table configures page layout • Inner table organizessome information on the page

  20. Checkpoint 8.3 1. Describe a reason to use a percentage width for a table that configures a web page layout. Provide an example of a page that uses this technique. 2. Describe a reason to use a fixed pixel width for a table that configures a web page layout. Provide an example of a page that uses this technique. 3. True or False. Tables can be nested within other tables.

  21. Using CSS to Style a Table

  22. Summary • This chapter introduced the XHTML techniques used to create and configure tables. • You will use these skills over and over again as you create Web pages.
